FLASH PROGRAM MEMORY
The dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/
X04, and dsPIC33FJ128GPX02/X04 devices contain
internal Flash program memory for storing and
executing application code. The memory is readable,
writable and erasable during normal operation over the
entire VDD range.
Flash memory can be programmed in two ways:
In-Circuit Serial Programming (ICSP)
programming capability
Run-Time Self-Programming (RTSP)
ICSP
allows
any
of
the
following
devices,
dsPIC33FJ32GP302/304, dsPIC33FJ64GPX02/X04,
and
dsPIC33FJ128GPX02/X04,
to
be
serially
programmed while in the end application circuit. This is
done with two lines for programming clock and
programming data (one of the alternate programming
pin pairs: PGECx/PGEDx), and three other lines for
power (VDD), ground (VSS) and Master Clear (MCLR).
This allows customers to manufacture boards with
unprogrammed devices and then program the digital
signal controller just before shipping the product. This
also allows the most recent firmware or a custom
firmware to be programmed.
RTSP is accomplished using TBLRD (table read) and
TBLWT (table write) instructions. With RTSP, the user
application can write program memory data either in
blocks or ‘rows’ of 64 instructions (192 bytes) at a time
or a single program memory word, and erase program
memory in blocks or ‘pages’ of 512 instructions (1536
bytes) at a time.
5.1
Table Instructions and Flash
Programming
Regardless of the method used, all programming of
Flash memory is done with the table read and table
write instructions. These allow direct read and write
access to the program memory space from the data
memory while the device is in normal operating mode.
The 24-bit target address in the program memory is
formed using bits <7:0> of the TBLPAG register and the
Effective Address (EA) from a W register specified in
the table instruction, as shown in Figure 5-1.
The TBLRDL and the TBLWTL instructions are used to
read or write to bits <15:0> of program memory.
TBLRDL and TBLWTL can access program memory in
both Word and Byte modes.
The TBLRDH and TBLWTH instructions are used to read
or write to bits <23:16> of program memory. TBLRDH
and TBLWTH can also access program memory in Word
or Byte mode.
